Bug #78169 [NEW]: preloading + require vs fatal error

From: nicolas dot grekas+php at gmail dot com Operating system: PHP version: 7.4.0alpha1 Package: opcache Bug Type: Bug Bug description:preloading + require vs fatal error Description: ------------ When opcache.preload is used, requiring twice a file that declares a preloaded class will not yield any error, while when preloading is not used, one will get a cannot redeclare error. On the other side, when require_once is used, a preloaded class file is not considered "already loaded", which means the require happens during execution. Would it make sense to change both these behaviors to make them more in line with normal engine behavior? i.e. "require_once" on a file that was already preloaded wouldn't require it again, and "require" on a preloaded file that contains a class declaration would yield a "cannot redeclare" fatal error? This would be more expected to me.
